7.54.26

yadi ca manujapannagāḥ piśācā rajanicarāḥ patagāḥ surāsurāśca |
raṇagatamabhiyānti sindhurājaṃ na sa bhavitā saha tairapi prabhāte || 26 ||

[paragraph continues] Drive away thy grief, O daughter, as thou shalt hear such agreeable news on the morrow. That which Partha hath vowed must be accomplished. It cannot be otherwise. That which is sought to be done by thy husband can never remain unaccomplished. Even if all human beings and snakes and Pisachas and all the wanderers of the night and birds, and all the gods and the Asuras, help the ruler of the Sindhus on the field of battle; he shall still, with them, cease to exist tomorrow.'"
